if' SPECIFICATION forming part of Letters Patent No. 481,327, datedAugust 23, 1892.

Application iiled February 16, 1892. Serial Nu. l21,716. (No model.)

To all whom it may concern:

Be itknown that I, FRANK A. HOILLENBECK a citizen of the United States,residing at Ba; tavia, in the county of Genesee and State of New York,have invented certain new and useful Improvements in Firearms; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention is an improvement in firearms; and it consists in certainnovelfeatures of construction and combination of parts hereinafter fullydescribed.

In the accompanying drawings I have shown one form in which I havecontemplated embodying my invention, and said invention is fullydisclosed in the following description and claims.

Referring to the said drawings, Figure l is a central sectional view ofa portion of the barrels and stock of a gun embodying my invention,showing the fore-end detached. Fig. 2 is a similar view showing thefore-end applied to the gun. Fig. 3 is a similar view showing the gunbent or broken,ready for reloading.

In the said drawings, A represents the barrel portion of the gun, and Bthe stock portion. The barrels A are provided with thedownwardly-extending coupling-lug a. in the usual manner, said lughaving a semicircular recess a to engage the pivot-bolt b of the stock,the lug a engaging a recess in the forwardly-projecting portion ot' thestock in the usual manner.

The lug aJ is provided with an inclined recess, preferably square orpolygonal in crosssection, in which is located the cooking-bolt C,provided at its upper end, adjacent to the barrels, with anupwardly-projecting lug or arm c, the said bolt being slightly longerthan the length of its recess. The cocking-bolt is provided with aspring, which tends to force it in a direction toward the muzzle of thegun, and I have shown this spring c located in an enlargement c2 of thepolygonal bolt-recess, the said spring engaging a shoulder c3 on thebolt C and being held in its recess by a screwplug ci. The breech-blockof the gun-stock B is provided with the pivotally-mounted cocking-leverD of usual construction, having an arm d, provided wit-h suitable meansfor engaging the `hammers of the gun, which are indicated in dottedlines. The cocking-leverD has an arm d', extending forward into thevicinity of the cocking-bolt and provided, it desired, with a recessedportion to provide a bearing-surface for engagement with the end of thecooking-bolt.

E is the shell-extractor, provided with the operating stem or rod e,which extends to a point adjacent to the lug or projection c of thecooking-bolt. lVhen the stock and barrels are placed together with thelug a. of the barrels engaging the pivot-bolt b and before the fore-endF has been placed in operative position, the parts w-ill be in thepositions shown in Fig. 1. The spring c will hold the cooking-bolt ontof engagement with the cocking-lever D and the lug c of the cooking-boltout of contact with the extractor-rod e, as will be clearly seen in thedrawings.

The fore-end F is constructed in the usual or ordinary manner, andsuitable means are provided to lock it to the barrels when in operativeposition. The rear portion of the fore-end is provided with aconstruction to engage the pivot-bolt b in the usual manner, and in thisrear portion is pivoted the ejector f, which is held in place in arecess provided for it by the pin f. This ejector fis provided with ashort straight side-f2, which is adapted to engage a solid portion b ofthe breech-block or stock adjacent to the bolt 1J, and said ejector isalso provided with a longer straight side f3, which is adapted to engagethe end of the cooking-bolt C when the foreend is placed in operativeposition upon the gun. It will be seen by reference to Figs. 1 and 2that when the fore-end is placed in engagement with the gun the ejectorf will engagel the forward end of the cooking-lever and move itlongitudinally as the fore-end is shoved into place upon the barrels.This longtudinal movement ofthe cooking-bolt causes its rear end toproject from its recess andengage the bearing-surface of theoperatingarm d of the cooking-lever D, and at the same time the lng orprojection c of the cock- -ing-bolt will be made to engage the stern eofthe extractor, as clearly shown in Fig. 2. The gun is then in conditionfor operation. XVhen the gun is opened or broken, as shown in Fig. 3,the ejector f will be held in a stationary position with respect to thestock or IOC breech-block, while the barrels will move `with respect tosaid ejector. In consequence the ejector Will act as a lever, being heldfrom `movement by the solid wall bx, and its face f3 will force thecooking-bolt C to move longitudinally and rearwardly. As the barrels aredepressed the rear end of the same Will rise and with it the lug a andcooking-bolt O, and the said cocking-bolt having been placed inengagement with the cooking-lever, as before stated,when the fore-endwas placed in position the arm d of the cockinglever will be raised,thereby forcing back the hammers and cooking the gun. The longitudinalmovement of the cooking-bolt prevents it from becoming disengaged fromthe arm d of the cooking-lever, which might otherwise occur by reason ofthe swinging of said cooking-lever on its pivot, as will be readilyunderstood. The longitudinal movement of the cookingbolt also effectsthe positive operation ofthe cartridge-shell extractor E, the lug cofthe bolt engaging the rod e of the extractor, as will be readily seen inFig. 3. When the gun is closed, the extractor Will be forced in, and byreason of its engagement with the lug c of the bolt C will positivelyreturn the bolt to its originalposition. (ShoWninFig.2.) Thespring c'would perform this function; but by this construction itis positivelyinsured by the extractor, even though the spring should become broken,and the breaking of the spring would not in the least affect the perfectand accurate operation of the gun. When it is desired to separate thebarrels and stock, the fore-end F is removed,when the spring c willforce the cocking-bolt forward longitudinally, disengaging it from thearm dof the cookinglever D and also from the extractor, so that thebarrels can be readily removed from the stock.

It will be observed that by my construction I provide a cooking-boltwhich positively and simultaneously operates both the cooking-1e- 1verand the extractor and which is positively returned toits originalpositionby the extractor, and I also provide means whereby the saidcooking-bolt can be instantly disconnected from the cooking-lever byremoving the fore-end.

I do not desire to be limited to my exact details of construction, asherein set forth and shown, for variations may be made therein `withoutdeparting from the spirit of my invention.

What I claim, and desire to secure by Letters Patent, is

1. In a firearm, the combination, with the cooking-lever and theshell-extractor, of a i cooking-bolt operatively connected with the saidcooking-leverand extractor, substantially as described.

2. In a firearm, the combination, with the cooking-lever and theextractor, of the longitudinally-movable cooking-bolt engaging saidextractor and the ejector engaging the said cooking-bolt, substantiallyas described.

3. In a firearm, the combination, with the extractor and cooking-lever,of the longitudinally-movable cooking-bolt engaging the said extractor,the spring engaging and moving the cocking-bolt in one direction, andthe ejector engaging and moving the said coclrL ing-bolt in the oppositedirection, substan- -tially as described.

4. In a firearm, the combination, with the cooking-lever pivotallysecured to the stock portion of the arm, of the cooking-bolt movablymounted in the barrel portion of the arm, a spring for moving said boltout of engagement with said lever, and the fore-end provided with meansfor retaining the cocking-bolt in constant engagement with thecooking-lever when said fore-end is placed in proper position upon thebarrel portion of the firearm, substantially as described.

5. In a firearm, the combination, with the cooking-lever, of thelongitudinally-movable cocking-bolt secured to and moving with thebarrels, a spring engaging said cooking-bolt and adapted to move it in adirection to disengage it from the cooking-lever, and the fore-endprovided with a construction to engage said bolt when the fore-end isattached to the gun and hold the cooking-bolt in constant engagementwith the cooking -lever against the force of said spring,substantiallyas described.

6. In a firearm, the combination, with the cooking-lever and extractor,of the longitudinally-movable cocking-bolt secured to and moving withthe barrels, having a portion operatively engaging the cooking-lever anda portion operatively engaging a part connected with the extractor, andmeans for positively moving said cooking-bolt longitudinally,substantially as described.

7. In a firearm, the combination, with the cooking-lever and theextractor, of the longitudinally-movable cooking-bolt secured to andadapted to move with -the barrels, having a part operatively engagingthe cookinglever and a portion operatively engaginga part connected withthe extractor, and the ejector for moving said cooking-boltlongitudinally whn the gun is broken to effect the operation of theextractor', substantially as described. t

8. In a firearm, the combination, with the cooking-lever pivoted in thestock and the extractor, of the cooking-bolt adapted to engage saidcooking-lever and extractor, the spring operatively engaging the saidcookingbolt, the fore-end, the ejector pivoted to the fore-end andhaving a part adapted to engage a. rigid port-ion connected with thestock, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
